[pbs-devel] [PATCH v2 proxmox-backup 2/2] add versions command to proxmox-backup-manager

[Mira Limbeck <m.limbeck@proxmox.com>]

Add the versions command to proxmox-backup-manager with a similar output
to pveversion [-v]. It prints the packages line by line with only the
package name, followed by the version and, for proxmox-backup and
proxmox-backup-server, some additional information (running kernel,
running version).

In addition it supports the optional output-format parameter which can
be used to print the complete data in either json, json-pretty or text
format. If output-format is specified, the --verbose parameter is
ignored and the detailed list of packages is printed.

With the addition of the versions command, the report is extended as
well.

v2:
    - removed the special casing for running kernel and running version
      as the get_versions result already contains the complete string
    - fixed version string to print 'not correctly installed' instead of
      'unknown' if no old_version is available
